Description

CodeGym — an AI-powered coding practice platform that goes beyond LeetCode/DSA. https://hackathon-vercel-gemini.vercel.app/ Stack: Next.js 16 + React 19, Supabase (Postgres), Google Gemini, Vercel Sandbox, Monaco Editor, BetterAuth What it does: Problem Generation — Gemini creates realistic, real-world coding problems (not DSA), complete with starter code, reference solution, test harness, and hints Real Code Execution — User code runs in a Vercel Sandbox against actual test cases (with a Node.js eval fallback) MCQ Marathon — Adaptive multiple-choice quizzes that target weak areas Chat memory insert — Currently the functionality is limited to the user inserting context into the system for the memory feature (to manually add memories) Skill Memory — A living AI-generated profile tracking domain scores (0-100), strong/weak skills, and interaction history. Every problem attempt, MCQ session, and chat updates the profile via Gemini Core loop: Generate problem → solve it → execute against real tests → AI updates your skill profile → next problem adapts to your weaknesses.

README excerpt

This is a [Next.js](https://nextjs.org) project bootstrapped with [`create-next-app`](https://nextjs.org/docs/app/api-reference/cli/create-next-app).

## Getting Started

First, run the development server:

```bash
npm run dev
# or
yarn dev
# or
pnpm dev
# or
bun dev
```

Open [http://localhost:3000](http://localhost:3000) with your browser to see the result.

You can start editing the page by modifying `app/page.tsx`. The page auto-updates as you edit the file.

This project uses [`next/font`](https://nextjs.org/docs/app/building-your-application/optimizing/fonts) to automatically optimize and load [Geist](https://vercel.com/font), a new font family for Vercel.

## Deploy on Vercel

The easiest way to deploy your Next.js app is to use the [Vercel Platform](https://vercel.com/new?utm_medium=default-template&filter=next.js&utm_source=create-next-app&utm_campaign=create-next-app-readme) from the creators of Next.js.
